GH2135 is an iron-nickel-based superalloy developed by our country. Its properties have reached and exceeded the level of nickel-based alloy gh33 except for its slightly lower fatigue performance. The alloy has good thermal processing plasticity, but the cutting performance is poor; after surface aluminizing, the anti-pamming performance is better. Practice has proved that the alloy is relatively mature and reliable in use. The use temperature is 500-1000ºC, and it is used to manufacture general load-bearing parts for aviation, aerospace, gas turbines and other industries.
